So, you wont cycle right now, you didn't mention that or I must have missed it. Good. Get your chit in order and then do it. But honestly, for such severe insomniacs, cycling wont bring anything good to the table. How do you even function day to day, can you keep a job, do you have a life, will cycling help with those things? Sleep is really the number one thing that is going to make or break your progress in the gym - I know, I'm speaking from personal experience. And if you get to a point where your sleep is improved and you're off your sleeping meds, that's a big achievement, and you need to nurture that state - adding aas to the mix would just unbalance the whole thing and you'd be back to square one. Don't know what's the reason you aren't sleeping and when the problem started but again, sleeping is #1 and if you took sleeping as your #1 priority and it started to improve, your fitness goals would start to improve. Cycling is a band aid, you could probably get half way to where you want to come with your cycle, if you just started sleeping like a "normal" human being. And then when you get there, then start using aas.
Regarding the pec injury and cycling in general, you could do a peptides stack for some time and add bpc157 to that. If anything, peptides will improve your sleep. Also check epitalon, it helps restore melatonin production and reduces plaque. There's a thread on meso called "A must for those who use Trenabolone ...", check it. Anyway, restore your pec health b4 you start cycling. Pec tears take a long time to heal. You might think it's ok, but then in a few months time it happens again.
Regarding your programming, it is very sub optimal. You are training each body part 1x a week. Train each body part at least 2x a week if not 3x. Your legs for instance, on cycle, by wednesday, they will be fully recovered, but you wont train them till next week, same with other body parts. You are missing on a lot of growth this way. Also, if you squeeze all your training volume in to one day, you are again, wasting a lot of volume. There is a volume threshold, where you wont get more growth, but are basically just fatiguing yourself. And you are probably doing that on every single training day. You've got no business training legs for a whole session, same goes with back, arms, chest, etc. Check out Mike Israetels explanation's about MRV - maximal recoverable volume. Check out SRA curves, check out how much volume do you actually need for a specific body part to stimulate hypertrophy and how much rest is needed before you can hit it again. Hint: it's 1 to max 3 days. Big and heavy compound moves like DL's will tax your CNS a lot, requiring more rest ... Anyway, adjust your training routine.
What do you want to achieve with your cycle? Cut, recomp, bulk? I see you stated a 200kcal surplus, but on a cycle that wont be a bulk but a recomp. So you plan on going from 15% bf down to 12% and gaining some muscle mass? How is your cycle plan looking for that? Recomp is the hardest to achieve and you need the strongest aas to do that. SD would be the perfect choice for that. Test isn't good enough, you need DHB or Primo or Tren (don't do tren you wont sleep at all), ... etc. You need high/effective dosages for that. You still got some thinking to do imo.
